我需要多次使用:[mutableDict addEntriesFromDictionary:dictionary];
我不知道如何在头文件中声明mutableDict 。我尝试:
@property (nonatomic, assign) NSMutableDictionary *mutableDict;
@property (nonatomic, 保留) NSMutableDictionary *mutableDict;
@property (nonatomic, retain, readwrite) NSMutableDictionary *mutableDict;
和更多...
我必须如何声明这个 NSMutableDictionary?
